<div id="cls-Ext.ux.StatusBar"></div>/**
 * @class Ext.ux.StatusBar
 * <p>Basic status bar component that can be used as the bottom toolbar of any {@link Ext.Panel}.  In addition to
 * supporting the standard {@link Ext.Toolbar} interface for adding buttons, menus and other items, the StatusBar
 * provides a greedy status element that can be aligned to either side and has convenient methods for setting the
 * status text and icon.  You can also indicate that something is processing using the {@link #showBusy} method.</p>
 * <pre><code>
new Ext.Panel({
    title: 'StatusBar',
    // etc.
    bbar: new Ext.ux.StatusBar({
        id: 'my-status',

        // defaults to use when the status is cleared:
        defaultText: 'Default status text',
        defaultIconCls: 'default-icon',

        // values to set initially:
        text: 'Ready',
        iconCls: 'ready-icon',

        // any standard Toolbar items:
        items: [{
            text: 'A Button'
        }, '-', 'Plain Text']
    })
});

// Update the status bar later in code:
var sb = Ext.getCmp('my-status');
sb.setStatus({
    text: 'OK',
    iconCls: 'ok-icon',
    clear: true // auto-clear after a set interval
});

// Set the status bar to show that something is processing:
sb.showBusy();

// processing....

sb.clearStatus(); // once completeed

     * @cfg {String} statusAlign
     * The alignment of the status element within the overall StatusBar layout.  When the StatusBar is rendered,
     * it creates an internal div containing the status text and icon.  Any additional Toolbar items added in the
     * StatusBar's {@link #items} config, or added via {@link #add} or any of the supported add* methods, will be
     * rendered, in added order, to the opposite side.  The status element is greedy, so it will automatically
     * expand to take up all sapce left over by any other items.  Example usage:
     * <pre><code>
// Create a left-aligned status bar containing a button,
// separator and text item that will be right-aligned (default):
new Ext.Panel({
    title: 'StatusBar',
    // etc.

    })
});

// By adding the statusAlign config, this will create the
// exact same toolbar, except the status and toolbar item
// layout will be reversed from the previous example:
new Ext.Panel({
    title: 'StatusBar',
    // etc.
